Chapter 4 Pre Test Flashcards
What are the functions and location of epithelial tissue?
Protection
Control permeability (absorption, excretion, filtration, diffusion)
Sensory function
Secretions
protection, secretion, [permeability - absorption, excretion, filtration, diffusion], and sensory reception.
DOES NOT *provide padding and a supportive framework for other tissue types
Location - skin and linings
Protective or filtration.
The lamina lucida: (a layer of the basal lamina)
contains glycoproteins and a network of fine protein filaments.
What tissue type is found along passageways in the kidneys, inside the eye, and in the alveoli of the lungs?
simple squamous epithelium
What tissue type is most common along the ducts of sweat glands, mammary glands, and other exocrine glands?
Stratified cuboidal epithelial tissue
Which of the following is NOT a characteristic of pseudostratified columnar epithelial tissue?
It includes several types of cells with varying shapes and functions.
*It may have multiple layers, with only the superficial cells being columnar.
It is not truly stratified because every epithelial cell contacts the basal lamina.
It typically has cells that possess cilia.
The seminiferous tubules of the testes are of which exocrine gland type?
compound tubular
Lymph is an example of which type of connective tissue?
*fluid connective tissue
dense connective tissue
epithelial tissue
loose connective tissue
The complex three-dimensional supporting network called “stroma” is found in:
reticular tissue.
Which type of blood cell promotes inflammation much like mast cells do in other connective tissues?
basophils
Which tissue type, found between the ends of ribs and the bones of the sternum, provides stiff but somewhat flexible support?
hyaline cartilage
Which of the following is CORRECT regarding bone tissue?
The cellular layer of the periosteum assists in the attachment of bone to the surrounding tissues.
Canaliculi are at the center of each osteon, providing oxygen and nutrients to the osteocytes.
Layers of matrix separate the tissue.
*Lacunae in the matrix contain osteocytes.
Which layer of fasciae forms a strong, fibrous internal framework?
deep fascia
Smooth muscle tissue cells:
are short, spindle-shaped, and nonstriated.
Skeletal muscle tissue cells:
are long, cylindrical, banded, and multinucleated.
Cardiac muscle tissue:
are short, branched, striated, and have a single nucleus. Cardiac muscle has intercalcated disks.
Which statement regarding the body’s response to tissue injury is false?
Fibrosis in muscle and other tissues may occur in response to injury, disease, or aging.
*Neural tissue regenerates well.
Damaged areas are often replaced by scar tissue.
Each organ has a different ability to regenerate after injury.
Which of the primary tissue types functions to store energy?
connective tissue
4 types of tissue
connective tissue
epithelial tissue
neural tissue
muscle tissue
An epithelium has a(n) _____ surface, which faces the exterior of the body or some internal space, and a basal surface, which is attached to adjacent tissues; the presence of such structural and functional differences between the exposed and attached surfaces is referred to as polarity.
apical
Intercellular attachments called
attach the deepest epithelial cells to the basal lamina.
hemidesmosomes
A stratified
epithelium is generally located where mechanical or chemical stresses are severe.
squamous
A simple
epithelium provides limited protection and occurs where secretion or absorption takes place.
cuboidal
At a gap junction, two cells are held together by interlocking junctional proteins called
.
connexons
A merocrine sweat gland is an example of a simple coiled
gland structure.
tubular
In appositional growth, the cartilage enlarges by the addition of cartilage to the outer surface, whereas in
growth, the cartilage expands from within.
interstitial
bone grows in LENGTH vs diameter; endochondral ossification
Which statement regarding glands is NOT correct?
Endocrine glands secrete hormones or hormonal precursors.
Glands are derived from epithelia, but secretory cells predominate.
Endocrine glands secrete into internal passageways that connect to the exterior.
Exocrine glands secrete onto external passages.
*Endocrine glands secrete into internal passageways that connect to the exterior.
Endocrine glands release secretion into interstitial fluid
Which intercellular attachment is very strong and resists stretching and twisting?
desmosomes (spot demosome)
Which tissue type is found lining the stomach, intestine, gallbladder, uterine tubes, and kidney ducts?
simple columnar epithelium
Adipose tissue is a type of:
loose connective tissue.
Support of the external ear is an example of which of the following?
elastic cartilage
Describe characteristics of serous membranes
They are exemplified by three membranes, which line the body cavities of the trunk - pleura, pericardium, and peritoneum
They are extremely delicate and are never directly connected to the exterior.
They consist of a mesothelium supported by areolar tissue.
Which tissue type moves the body by pulling on bones?
skeletal muscle tissue
____ columnar epithelia are relatively rare, and are most often found lining large ducts such as those of the salivary glands or pancreas.
stratified
______ secretion involves the loss of cytoplasm as well as the secretory product.
apocrine
The three basic components that all forms of connective tissue share are specialized cells, extracellular protein fibers, and a fluid known as ground substance, which, together with the extracellular fibers, constitute the ______ that surrounds the cells.
matrix
______ tissue is the most common form of connective tissue proper in adults. It contains all of the cell types found in other forms of connective tissue proper: extracellular fibers; wandering cells; fixed cells such as melanocytes, fixed pigment cells that synthesize melanin; and fibroblasts, fixed cells that synthesize the extracellular fibers of the connective tissue.
areolar
